Ingesting high concentrations of Na+ (100 mEq·l-1) during prolonged exercise positively affects fluid balance.
Practitioners may consider recommending high Na+ concentrations in carbohydrate solutions for athletes during prolonged exercise.
StrongSupportsmedium confidence
We conclude that the addition of high (100 mEq·l-1) concentrations of Na+ to a CHO solution ingested during prolonged exercise has a positive effect on fluid balance.
Why this rating
The study involves controlled exercise trials with specific Na+ concentrations.
